When ppl say it's "normal", they mean that this issue won't cause your car to swerve off the road all of a sudden or make the car drive any worse. Car still operates fine, it just makes a noise.
I hate it when ppl come on to these forums, don't get an answer that they expect and make a huge fuss about it. Just because it isn't what you expected, doesn't mean the answer is any less useful. If you don't like what someone else tells you, go do something about it yourself.
